Coronavirus mutations unlikely to mean stronger strain: experts

The coronavirus' constant mutation is unlikely to have changes its potency or its contagiousness, disease experts say, despite recent research suggesting the emergence of a more virulent strain. A pre-paper -- that is, not reviewed by a collection of the researchers' peers -- released last month by Los Alamos National Laboratory claimed to have identified a new strain of the virus. A mutation on one of the virus' protein spikes made the strain currently circulating in Europe and the United States potentially more potent than the one that emerged from China at the end of last year, the authors claimed. "The mutation Spike is of urgent concern; it began spreading in Europe in...
